Approximating L^2-signatures by their compact analogues
Wolfgang Lueck, Thomas Schick
:Let G be a group together with an descending nested sequence of normal subgroups G=G_0, G_1, G_2 G_3, ... of finite index [G:G_k] such the intersection of the G_k-s is the trivial…

The spectral measure of certain elements of the complex group ring of a wreath product
Warren Dicks, Thomas Schick
We use elementary methods to compute the L2-dimension of the eigenspaces of the Markov operator on the lamplighter group and of generalizations of this operator on other groups. In…

Approximating L2-invariants, and the Atiyah conjecture
Jozef Dodziuk, Peter Linnell, Varghese Mathai +2
Let G be a torsion free discrete group and let \bar{Q} denote the field of algebraic numbers in C. We prove that \bar{Q}[G] fulfills the Atiyah conjecture if G lies in a certain cl…
